The third reason is that at the time that Turkic Muslims were waging rebellion in the early years of the Guangxu reign, the ‘five elite divisions’ that governor general Liu Jintang led out of the Pass were all Dungan troops [Hui dui 回队]. Back then, Dungan military commanders such as Cui Wei and Hua Dacai were surrendered troops who had been redeployed. These are undoubtedly cases of pawns who went on to achieve great merit. When Cen Shuying was in charge of military affairs in Yunnan, the Muslim troops and generals that he used included many rebels, and it was because of them that the Muslim rebellion in Yunnan was pacified. These are examples to show that Muslim troops can be used effectively even while Muslim uprisings are still in progress. What is more, since the establishment of the Republic, Dungan have demonstrated not the slightest hint of errant behaviour to suggest that they may prove to be unreliable.
